20 provinces is alot to manage!! but this would not be for begginers or the faint hearted. as for the armies, well depending on the players it could go either way. if people who grew quickly only attacked smaller players, then the armies would become insanly huge, but eventually they would clash (i would like to see that battle report!!). though, if this relm were to happen, i would definatly be there and would do my best to focus on bringing down the strong, not annoying the weak with 20 attacks a day. hmmmm another thought...no army upkeep for troops at home, field or garrisoned (to offset, the upkeep of a travaling army could be twice what it is now, and take away the option of having troops at home not participate in a field battle...so if someone Field Attacks you, if you have troops in the province, they will fight no matter what)! why? why not!!
this relm would be about Chaos, huge armies, battles of sizes never seen before, and the ability to rebuild armies faster than ever before imagined!! take out a big player and think there done for awhile? Wrong!! they will be attacking you again within the month! well maybe...i would!!
